INTRODUCTION Polytetrafluoroethylene is ubiquitous in materials commonly used in cooking and industrial applications. Overheated polytetrafluoroethylene can generate toxic fumes, inducing acute pulmonary edema in some cases. However, neither the etiology nor the radiological features of this condition have been determined. For clarification, we report an illustrative case, together with the fir...

BACKGROUND AND OBJECTIVES The aim of this study was to report preliminary data on pregnancy outcomes after myomectomy with placement of an expanded polytetrafluoroethylene adhesion barrier membrane. METHODS In this retrospective case series, 68 women who underwent myomectomy with expanded polytetrafluoroethylene membrane placement between January 1, 2003, and December 31, 2009, were identifie...

C overed stents are composed of fabric or synthetic material supported by a metal mesh or stent platform. Although initially conceived to exclude peripheral arterial aneurysms and treat vessel perforations, the use of covered stents has expanded to act as a barrier to neointimal formation by excluding the vessel wall from the lumen. One such device is the Viabahn Endoprosthesis (Gore & Associat...

HYPOTHESIS An experimental polymeric sealant (CoSeal [Cohesion Technologies, Palo Alto, Calif]) provides equivalent anastomotic sealing to Gelfoam (Upjohn, Kalamazoo, Mich)/thrombin during surgical placement of prosthetic vascular grafts. DESIGN Randomized controlled trial. SETTING Nine university-affiliated medical centers. PATIENTS One hundred forty-eight patients scheduled for implanta...

OBJECTIVES We sought to evaluate the utility of the JOSTENT polytetrafluoroethylene (PTFE) stent-graft (Jomed GmbH, Rangendingen, Germany) in patients with diseased saphenous vein grafts (SVGs) undergoing percutaneous coronary intervention (PCI). BACKGROUND Prior trials of the JOSTENT stent-graft did not mandate high-pressure implantation or prolonged dual antiplatelet therapy, and were limit...
